2.2 Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic blood-
pressure is over 160 mmHg. In this case, please consult your doctor immediately. Long-term values at this
level endanger your health due to the associated advancing damage to the blood vessels in your body.
Should the systolic blood-pressure values lie between 140 mmHg and 160 mmHg and/or the diastolic
blood-pressure values lie between 90 mmHg and 95 mmHg, likewise, please consult your doctor. Further-
more, regular self-checks will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 105 mmHg and/or diastolic values
under 60 mmHg, likewise, please consult your doctor.
Even with normal blood-pressure values, a regular self-check with your blood-pressure monitor is recom-
mended. In this way you can detect possible changes in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, please keep a record of the level of
your blood pressure by carrying out regular self-measurements at specific times of the day. Show these va-
lues to your doctor.
Never use the results of your measurements to alter independently the drug
doses prescribed by your doctor.

Further information
•
If your values are mostly standard under resting conditions but exceptionally high under conditions of
physical or psychological stress, it is possible that you are suffering from so-called «labile hypertensi-
on». Please consult your doctor if you suspect that this might be the case.
•
Correctly measured diastolic blood-pressure values above 120 mmHg require
immediate medical
treatment.
2.3. What can be done, if regular increased/low values are obtained?
a)
Please consult your doctor.
b)
Increased blood-pressure values (various forms of hypertension) are associated long- and medium term
with considerable risks to health. This concerns the arterial blood vessels of your body, which are
endangered due to constriction caused by deposits in the vessel walls (Arteriosclerosis). A deficient
supply of blood to important organs (heart, brain, muscles) can be the result. Furthermore, with
long-term continuously increased blood-pressure values, the heart will become structurally damaged.

Introduction
1.1. Features of the BP 3BTO-H
The blood-pressure monitor BP 3BTO-H is a semi-automatic, digital blood-pressure measuring device for
use on the upper arm, which enables very fast and reliable measurement of the systolic and diastolic blood-
pressure as well as the pulse frequency by way of the oscillometric method of measuring.
The device offers a very high and clinical tested measurement accuracy and has been designed to provide a
maximum of user-friendliness.
Thanks to the large LCD display of BP 3BTO-H, both operational status and cuff pressure are visible for the
entire duration of the measurement.
Before using, please read through this instruction manual carefully and then keep it in a safe place. For furt-
her questions on the subject of blood-pressure and its measurement, please contact your doctor.
Attention!
1.2. Important information about self-measurement
•
Do not forget:
self-measurement means Control
, not diagnosis or treatment. Unusual values must
always be discussed with your doctor.
Under no
circumstances should you alter the dosages of any
drugs prescribed by your doctor.
•
The pulse display is
not
suitable for checking the frequency of heart pacemakers!
•
In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only be
evaluated after consultation with the doctor.
Electromagnetic interference:
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong electrical or
electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave cookers).
These can lead to temporary impairment of the measuring accuracy.

Important information on the subject of blood-pressure and its measurement
2.1. How does high/low blood-pressure arise?
The level of blood-pressure is determined in a part of the brain, the so-called circulatory centre, and
adapted to the respective situation by way of feedback via the nervous system.
To adjust the blood-pressure, the strength and frequency of the heart (Pulse), as well as the width of circu-
latory blood vessels is altered. The latter is effected by way of fine muscles in the blood-vessel walls.
The level of arterial blood-pressure changes periodically during the heart activity: During the «blood ejec-
tion» (Systole) the value is maximal (systolic blood-pressure value), at the end of the heart’s «rest period»
(Diastole) minimal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in order to prevent particular diseases.
